water efficient plumbing fixtures

HB 2253 sets water efficiency standards for plumbing fixtures in Arizona, affecting builders, contractors, and property owners installing new or replacing fixtures in residential and commercial buildings. It requires all new residential plumbing fixtures (like faucets, showers, toilets, and urinals) to use no more than 3 gallons per minute for faucets/showerheads and 1.6 gallons per flush for toilets, while commercial fixtures must meet stricter limits (e.g., automatic shut-off for faucets). The bill mandates that fixtures must either be Watersense-labeled or meet pre-2027 water efficiency criteria, and it specifically requires water-free urinals in new state buildings. These standards take effect January 1, 2027, aiming to reduce water consumption in both residential and public infrastructure.
